Assignments of the High Power Optically Pumped CW Laser Lines of Methyl Alcohol.

摘要

Thirteen far IR laser lines in CH3OH, optically pumped by a CO2 laser, have been assigned to a- and b-type transitions in nu sub 5 CO-stretch band. Identification procedures used were: a frequency match between the CO2 pump and CH3OH absorption, frequency match of laser lines and CH3OH nu sub 5 transitions, polarization of far IR radiation, cascade and competition effects between far IR laser lines, and frequency consistencies. An improved set of molecular constants for nu sub 5 transitions were also obtained. (Author)
